古洞口（Ⅰ級）水利水電工程(cheng)位于湖北省興(xing)山縣境內，壩址在長(chang)江支流香溪河(he)上游古夫河(he)段的古洞口峽谷(gu)出口處，下距(ju)興(xing)山縣新縣城(cheng)古夫鎮2.5公(gong)里(li)，距(ju)縣城(cheng)高陽(yang)鎮18.5公(gong)里(li)，為古夫河(he)流域水電開發的近期骨干工程(cheng)。

古洞口工(gong)程泄洪兼放(fang)空洞位于(yu)大壩左岸，圓塔(ta)式進水(shui)口的進口檢修閘室(shi)底板(ban)高程270.0米(mi)，弧形閘門位于(yu)隧(sui)洞中部(bu)，隧(sui)洞全長421米(mi)，均采用鋼筋砼襯(chen)(chen)砌(qi)，上游有壓段(duan)長183米(mi)，襯(chen)(chen)厚0.6米(mi)，由兩段(duan)方圓漸變段(duan)與檢修塔(ta)和(he)工(gong)作(zuo)閘室(shi)相接。下(xia)游無壓段(duan)長175米(mi)，出口采用斜切坎挑流消(xiao)能(neng)。要(yao)求(qiu)泄洪洞鋼筋砼施工(gong)必須保證(zheng)質量，滿足抗沖(chong)、抗滲功(gong)能(neng)的要(yao)求(qiu)，做(zuo)到澆筑密實、表面(mian)平整光滑。

古洞(dong)口工程為Ⅱ等(deng)大(da)（2）型工程，主要(yao)由攔(lan)河壩(ba)(ba)、泄(xie)洪建筑(zhu)物、引水(shui)系統(tong)、廠(chang)(chang)房及開(kai)(kai)關(guan)站組(zu)成。壩(ba)(ba)址處河道(dao)峽窄,兩岸(an)巖坡陡竣(jun),河床覆(fu)蓋層較深。且河道(dao)自峽谷出口處急轉向(xiang)右，右岸(an)下(xia)游地(di)勢開(kai)(kai)闊，交通方便(bian)。根據(ju)壩(ba)(ba)址地(di)形、地(di)質特點、及樞紐(niu)布置要(yao)求，泄(xie)洪建筑(zhu)物（即溢洪道(dao)和泄(xie)洪兼(jian)放空隧(sui)洞(dong)）布置在左岸(an)，引水(shui)系統(tong)及電站廠(chang)(chang)房布置在右岸(an)。

1、泄洪兼放空隧(sui)洞

泄洪(hong)兼放空隧(sui)洞位于(yu)大壩左岸，由進(jin)水(shui)口、有壓(ya)段(duan)、工作閘室、無壓(ya)段(duan)及末端(duan)挑流鼻坎組成(cheng)，全長421米，進(jin)水(shui)口底板高程為270米，校核洪(hong)水(shui)位時最大泄量1250立方米/秒(miao)。

根據中華人民共和國《防洪(hong)標準》GB50201-94規定，古洞口（Ⅰ級）水利(li)水電工(gong)程(cheng)永久建筑(zhu)物洪(hong)水標準為：

混凝土(tu)面板堆石壩(ba)設計(ji)洪(hong)(hong)水重現(xian)期為(wei)(wei)100年，校核洪(hong)(hong)水重現(xian)期為(wei)(wei)5000年。

廠房洪(hong)水重(zhong)現期為100年(nian)(nian)，校核洪(hong)水重(zhong)現期為200年(nian)(nian)。

混凝(ning)土面板堆石壩(ba)按(an)1級建筑(zhu)物設計，洪水標準按(an)2級建筑(zhu)物設計；

泄水建(jian)筑物(wu)按(an)2級建(jian)筑物(wu)設計(ji)；

引水建(jian)筑物(wu)及(ji)發電廠(chang)房按3級建(jian)筑物(wu)設計。

古(gu)洞口(kou)電(dian)站(zhan)下距新縣城所在(zai)(zai)地僅2.5公里，為了(le)(le)保證下游人(ren)(ren)員(yuan)、財(cai)產的(de)安全，同時也為自身建筑(zhu)物的(de)防(fang)(fang)(fang)洪(hong)需要，歷年(nian)來設計單位(wei)中(zhong)南勘測設計院以(yi)文件(jian)報(bao)送了(le)(le)《湖(hu)北香(xiang)溪河古(gu)洞口(kou)（Ⅰ級）水利水電(dian)工(gong)(gong)程(cheng)(cheng)渡(du)(du)汛(xun)意見》。按照要求(qiu)，電(dian)業(ye)公司每(mei)年(nian)均認(ren)真(zhen)組(zu)織編織了(le)(le)《古(gu)洞口(kou)水庫渡(du)(du)汛(xun)方(fang)案的(de)報(bao)告》，并(bing)上報(bao)各(ge)級防(fang)(fang)(fang)洪(hong)抗旱(han)指(zhi)揮部(bu)門。在(zai)(zai)接(jie)到(dao)報(bao)告批復(fu)后(hou)，按照批復(fu)文件(jian)要求(qiu)認(ren)真(zhen)落實(shi)人(ren)(ren)員(yuan)、機(ji)械和物資，并(bing)成立了(le)(le)以(yi)業(ye)主(zhu)、監理、各(ge)施工(gong)(gong)單位(wei)責任(ren)人(ren)(ren)和相(xiang)關人(ren)(ren)員(yuan)組(zu)成的(de)"古(gu)洞口(kou)工(gong)(gong)程(cheng)(cheng)防(fang)(fang)(fang)汛(xun)指(zhi)揮部(bu)"。電(dian)業(ye)公司成立了(le)(le)"防(fang)(fang)(fang)洪(hong)搶(qiang)險(xian)突擊(ji)隊"，各(ge)施工(gong)(gong)單位(wei)也成立了(le)(le)相(xiang)應機(ji)構，落實(shi)了(le)(le)各(ge)種措施。由于(yu)工(gong)(gong)程(cheng)(cheng)按渡(du)(du)汛(xun)要求(qiu)完成了(le)(le)工(gong)(gong)程(cheng)(cheng)項目(mu)施工(gong)(gong)，各(ge)方(fang)面配(pei)合(he)緊密，歷年(nian)來沒有發生工(gong)(gong)程(cheng)(cheng)防(fang)(fang)(fang)洪(hong)渡(du)(du)汛(xun)損失。
